We are using high precision micro-motors that imported from Germany. There are 2 micro-motors in the thumb, and the other 4 fingers each have 1 micro-motor. The motor is able to offer 120N (~27lbs in weight) grip power for each digit and is combined with our high precision turbine shaft to support the movement of digits. We offer all the components for the repair, but it really depends on whether the prosthetist/clinic will feel comfortable to change the components themselves. Everything can always be sent back to us, and we will offer a loaner hand to the user.
Our prosthetic hand is not 3d printed. 3d printed materials are not strong and stable enough for what our hand needs to help a user accomplish. We are using aviation-level aluminum alloy and food-grade plastic as our hand materials. We have an electrode system that comes with the hand to obtain the users’ EMG signals in their forearms.
- The pace at which each individual gains this control varies.
Depending on the condition of your limb, it may take several months to achieve confident and natural use of a prosthesis. Short-term and long-term goals should be jointly agreed between you and the clinicians involved in your care.
Initial wearing periods should be no longer than 15 to 30 minutes, with frequent examination of the skin for excess pressure or poor socket fit.
If no skin problems are present, wearing periods may be increased in 30-minute increments three times a day. By the end of a week, you may be comfortable wearing your prosthesis all day.
Always start with simple activities and gradually increase the complexity as your skill levels and confidence grow.
Remember that learning to relax is as important as opening and closing the prosthesis.
In terms of the hand’s capabilities, it is possible to operate a motor vehicle with the BrainRobotics prosthetic hand after sufficient proficiency is achieved. However, you will need to consult your local authorities to ensure it is legal for you to operate a car or bike in your country, state or city. In many cases, only vehicles with an automatic transmission may be operated.
We currently do not provide gloves/coverings with our prosthetic hand but always welcome user feedback!
Depending on your occupation, you should be able to return to work with your prosthesis but please consider any local laws involving the operation of heavy machinery, driving a vehicle of any kind, etc.
If the socket of your prosthesis fits well over the long term and no difficulties arise, you may not need a new prosthesis.
